Just recently got my hands on a trailblazer with the atlas i6 myself. Such solid motor with a good amount of power although not very good on gas for a 6 cylinder (still better than the 89 Ford I had before haha). I’ve been doing as much maintenance as I can, do to its high mileage, that my wallet will allow lately. A…
hell of an engine, hell of an article
Boy would it be nice if we civilian off-road enthusiasts had access to such machinery—it would make our mud-pit extraction operations a heck of a lot more interesting.
Good series, man. Keep it coming.

The air force also does a great job going the other way and air dropping Hummers.
Danggit guys! You’re making me miss my 04 Trailblazer. The engine was still running great at 252k miles. Only got rid of it because I needed a commuter car with better gas mileage and didn’t want to pay more than the car was worth replacing the timing chain. All the praise people are saying is true. It was quick and…
the end of that video though lol
GM: We made this great new Inline 6, lets stick it in 1 forgettable platform, and make another platform not big enough to fit it so it has to be chopped down by 1 cylinder.
I just want to say I approve your first point.
I have a list, in no particular order:
They were strong, but then they were tied to 4-speed transmissions. Problem #1.
I always thought the 5-cylinder engines were a weirder choice for an american company... but yes the Atlas engines are relatively unknown, probably due to GM branding just about anything as Vortec and only using these in essentially 2 vehicles
We have a 2004 Envoy and the Atlas has been fantastic. Smooth, (relatively) powerful, and dead reliable.
I mean, the AMC 4.0L did pretty good for being older than dirt and still kicking the competitions’ collective asses when it was released in the Cherokee.
I had an ‘03 Trailblazer with that 4200. If you stomped the throttle at 30mph, it would grab first and you were off to the races. And I must say, the Trailblazer had the best turning radius ever.
I remember taking a ride in a coworker’s trailblazer to lunch some years ago, and in the midst of shuddering at the horrible interior, was taken aback at just how that 4.2L ripped away from a light. Sure it was a bit unrefined in terms of sound, but also very smooth from the inherent balance.
I love the Atlas engines. I’m still a bit sour that GM chose not to continue them. It would have made an awesome base motor in the new 2007 full-size trucks, and I think that if they had made a reduced height, direct injected version, it could have done a lot of killing as the base engine in the 5th gen Camaro.
I saw an Isuzu Ascender the other day!
I know a lady that dropped one of these in her 1950 Pontiac because she did not want *just another damn V8 swap*. All in all it works beautifully and gets the old Pancho moving quickly.
